摘要:
This equipment includes at least one U-shaped clip (1) whose lateral branches (10) have sections and widths such that they may be inserted in the vertebral bodies (100) of two vertebrae by impaction on the intermediate branch (11) of the clip (1), so as to rest along the cortical bones of the vertebral bodies, and whose intermediate branch (11) is deformable in such a way as to allow a reduction of the distance between the lateral branches (10); the intermediate branch, before implantation, has a length such that one of the lateral branches (10) may be positioned slightly above the cortical bone forming the plate of the subjacent vertebra while the other lateral branch (10) may be positioned slightly below the cortical bone forming the plate of the subjacent vertebra, and has, after deformation, a length such that the two lateral branches (10) may be brought closer to each other.

摘要:
A graft or an intervertebral piece or cage designed to be inserted between two vertebrae, and an implant in the form of a staple, having two lateral branches designed to be inserted into the plates of the respective vertebrae to be immobilized and a central branch connecting these two lateral branches to each other. At least one lateral branch has at least one mobile portion, movable between an introduction position, in which this mobile portion is located in the extension of the rest of this lateral branch, and an anchoring position, in which this mobile portion protrudes laterally in relation to the rest of the lateral branch, and the implant has movement means allowing the mobile portion to move between the introduction and anchoring positions.
摘要:
An implant that allows immobilization of one vertebra in relation to another, having two lateral walls essentially parallel one with respect to the other and having a length, and at least one transverse wall connecting these lateral walls one to the other, at least one of these lateral walls having, on its side facing the side opposite the other lateral wall, slide prevention reliefs. The invention, the implant has, in a direction perpendicular to the length of the lateral walls, a dimension such that its two lateral walls are capable of coming into the immediate vicinity of the unci of the underlying vertebrae, the slide prevention reliefs of each of lateral wall thus being able to bear against the internal surface of the uncus of the underlying vertebra adjacent this lateral wall.

摘要:
This equipment includes: bony anchoring members whereof at least one includes a proximal threaded stud for receiving a nut and a base portion for anchoring to a vertebra; one or two linking rods to be connected to the anchoring members and be attached to the vertebrae thereby parts for connecting the linking rod(s) to the anchoring members, and extension pieces for engaging on the proximal stud(s) of the anchoring member(s) for running down connecting parts on the stud(s) until they rest on the proximal zone(s) of the base portion(s) of the anchoring members. The stud of at least one anchoring member and the extension piece used therewith include positioning elements.
摘要:
Equipment includes bony anchoring members one or two linking rods to be connected to the anchoring members and be attached to the vertebrae by dint thereof, parts for connecting the linking rod(s) to the anchoring members, and clamping elements for locking the linking rod(s) in the connecting parts; at least one anchoring member includes one proximal stud articulated with respect to a body for gripping a vertebra. The proximal stud exhibits an articulation head in the form of a spherical cap; and the anchoring member body includes a cavity for accommodating the articulation head and a wall surrounding this cavity, this wall being crimped around the articulation head and shaped to provide a proximal form, at least partially hemispherical.

Equipment includes bony anchoring members one or two linking rods, intended to be connected to the anchoring members, and parts for connecting the linking rod(s) to the anchoring members, at least one anchoring member including a proximal threaded stud and a clamping element for assembling a connecting part thereon, the connecting part including a clamping element for immobilizing the linking rod with respect thereto. The connecting part includes a rounded section for hugging a linking rod and two parallel branches having holes enabling engagement on the proximal threaded stud of the anchoring member; and the clamping elements may be engaged coaxially on the proximal threaded stud of the anchoring member, a first clamping element enabling the assembly of the connecting part on this proximal threaded stud and the second clamping element enabling to clamp both branches of this connecting part.
